This is the MINI portable OLED T12 soldering iron station, does not include the supply,Please use 3-5A supply to drive this soldering station,The high temperature of the iron tip cannot work continuously, and high temperature work can easily damage the tip The melting point of ordinary solder is 183 degrees, the melting point of lead-free solder is 227 degrees, the usual soldering temperature is 300-380 degrees, and the boundary temperature is 380 degrees, which is higher than 380 degrees. The oxidation and loss of the soldering iron tip are extremely fast and seriously affect the long life of the heating core. The temperature display will jump at 380 degrees, the higher the temperature, the bigger the jump If you can use low temperature, don't use high temperature: T12 is a constant temperature control. Generally, it is recommended that the working temperature be controlled between 300 Celsius and 380 Celsius. Higher than 380 Celsius will damage the tip coating and shorten the PTC life We do not recommend the use of an adjustable DC supply, because the adjusted adjustable DC supply cannot meet the requirements of an instantaneous supply. T12 has special requirements for supply. Instantaneous needs to reach 72W or higher. Certain of stabilized supplies cannot meet this requirement. As a result, it was impossible to the 942 soldering station.You need to purchase a DC 24V 3A-5A supply separately.Colour:blackMaterial:plasticPackage Contents:1 set * soldering stationOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
